Ratings and reviews

After struggling for two hours I couldn't add a single QR code in this app. If I connect my Yubikey 5C NFC - the "Add account" button disappears. If I disconnect the key, the Add account button works but then I can't save the form as it asks to attach the key and if I do - it crashes with some cryptic black message that I cannot read as it disappears.

Well at first I was angry because it wouldn't work on my Samsung S25 but then I disabled OTP and it works...next problem is the NFC issue but at least it works. Honestly this is really just Google and Samsung's fault for not cooperating. Edit: Okay I figured it out. I need to make a USB passkey first, then USB U2F, then a NFC U2F. I just noticed the toggles in the app Home tab top right too as I wrote this...that would have been useful to know! Particular but I'm happy I did it 🥲

A great, open-source authenticator from a company focused on security and privacy. This app is non-invasive (requiring minimal permissions, only Camera for QR codes and NFC). Made to work for the physical key and is all done on the device, It is simple and does its job as intended, with no unnecessary features or advertisements. Highly recommended for its transparency and simplicity.
